Magnetoencephalographic mapping of interictal spike propagation: a technical and clinical report

AJNR Am J Neuroradiol. 2007 Sep;28(8):1486-8. doi: 10.3174/ajnr.A0596.

Abstract

Distinguishing propagated epileptic activity from primary epileptic foci is of critical importance in presurgical evaluation of patients with medically intractable focal epilepsy. We studied an 11-year-old patient with complex partial epilepsy by using simultaneous magnetoencephalography (MEG) and electroencephalography (EEG). In EEG, bilateral interictal discharges appeared synchronous, whereas MEG source analysis suggested propagation of spikes from the right to the left frontal lobe.
